Solution: Count Subarrays With Fixed Bounds

Explore the two pointers technique to efficiently count subarrays that have fixed minimum and maximum bounds within an integer array. Understand how to track critical positions while iterating once through the array to identify valid subarrays that meet specified constraints without extra space.

Statement

Given an integer array, nums, and two integers minK and maxK, return the number of fixed-bound subarrays.

A subarray in nums is called a fixed-bound subarray if it satisfies the following conditions:

  1. The smallest value in the subarray equals minK.

  2. The largest value in the subarray equals maxK.

Note: A subarray is a contiguous sequence of elements within an array.

Constraints:
